eXplain vs. Rocket COBOL Analyzer vs. Kuscos vs. DeepSource

eXplain is a powerful solution crafted by PKS Software GmbH designed for analyzing code and evaluating legacy systems, particularly focused on conducting thorough assessments of legacy applications on mainframe platforms, such as IBM i (AS/400) and IBM Z. This software provides organizations with valuable insights into the software's structure, content, and helps identify which components could be retained, upgraded, or deprecated. By allowing users to import existing source code into a dedicated "eXplain server," the tool removes the need for installations on the host system and employs advanced parsers to analyze several programming languages, including COBOL, PL/I, Assembler, Natural, RPG, and JCL. Additionally, it examines relevant information from databases like Db2, Adabas, and IMS, as well as job schedulers and transaction monitors. eXplain establishes a centralized repository that acts as a knowledge repository, generating cross-language dependency graphs, data-flow diagrams, interface evaluations, groupings of related modules, and detailed reports on resource and object utilization. This functionality enables users to visualize the interrelationships within their code, thereby deepening their comprehension of the software ecosystem. Furthermore, by providing a clearer understanding of their legacy systems, eXplain equips organizations with the tools needed to make strategic decisions about their software's future. Ultimately, the tool enhances operational efficiency and drives informed technological advancements.

Understanding large, complex applications should not rely on guesswork. Rocket® COBOL Analyzer™ is a comprehensive code analysis and visualization solution designed to provide clear visibility into your entire application portfolio. It enables executives, developers, and analysts to quickly understand complex business logic, relationships, and dependencies across the codebase. By transforming intricate code structures into intuitive visual insights, the platform allows IT teams to plan and execute changes with confidence and precision. It offers the ability to visualize application dependencies at scale, supporting a complete and accurate understanding of system architecture. With integrated GenAI-powered insights, teams can accelerate decision-making, improve project planning, and reduce the time required to analyze critical systems. The platform also helps protect business operations by allowing teams to assess and predict the impact of code changes before they are implemented. This approach reduces uncertainty, minimizes risk, and supports safer modernization of COBOL environments. It provides a more intelligent and controlled way to manage, maintain, and evolve mission-critical applications.

Kuscos emerges as the leading software intelligence platform, whether you are exploring enhancements to a legacy Cobol system from the 90s or looking for sophisticated tactics to advance your C# development projects. It equips development teams, managers, and executives with essential insights into source code modules and team interactions, addressing elements ranging from design documentation and dependencies to duplicate code and violations of quality standards. Furthermore, Kuscos tracks team activities comprehensively, monitoring everything from repository commits to the resolution of various issues, thus providing a holistic view of project progress. Astonishingly, it manages this across more than 16 different programming languages, both legacy and modern. As discussed previously, the Standish Group reports that only 29% of software projects have succeeded in achieving their timelines, budgets, and functional goals over the past five years. Despite the evolution of coding practices and design strategies, the overall rate of project success remains disappointingly low. This highlights an urgent demand for improved management tools, a gap that Kuscos effectively fills, ensuring that teams can navigate projects more efficiently and with greater accountability. With its comprehensive capabilities, Kuscos is poised to revolutionize the way software development projects are managed and executed.

DeepSource is an AI-powered platform designed to automate code reviews and help engineering teams build more secure and reliable software. It uses a hybrid analysis approach that combines deterministic static code analysis with advanced AI review agents to examine code changes. The platform integrates seamlessly with development environments such as GitHub, GitLab, Bitbucket, and Azure DevOps, enabling automatic analysis of pull requests. Each code change is scanned for bugs, security vulnerabilities, performance risks, complexity issues, and maintainability concerns. Developers receive inline comments and structured review summaries that explain problems and suggest improvements. The system includes Autofix capabilities that generate verified patches for many detected issues, allowing developers to resolve problems quickly. DeepSource also monitors dependency vulnerabilities using reachability and taint analysis to identify which open-source risks actually affect the codebase. Security tools detect exposed secrets, API keys, and credentials before they reach production environments. Infrastructure-as-code scanning helps identify configuration weaknesses in Terraform and CloudFormation files. Teams can track test coverage to ensure new code is properly tested before merging. Compliance reports map vulnerabilities to recognized security standards such as OWASP Top 10 and SANS Top 25. The platform also offers full codebase scanning to identify long-term quality and security issues across existing repositories. By combining automation, security intelligence, and actionable feedback, DeepSource enables organizations to scale development without sacrificing code quality.
